CompTIA Network+ (N10-006) — Question 62

An employee of a highly secure company needs to use facial recognition in addition to username/password to successfully establish a VPN.
Which of the following describes this methodology?

Answer options

• A. PKI
• B. Federated identity
• C. Two-factor authentication
• D. Biometric authentication
• E. AAA

Correct answer: A

Explanation

The correct answer is A, PKI, which stands for Public Key Infrastructure, providing a framework for secure communications. However, the scenario primarily illustrates the use of multiple authentication methods, which is best captured by C, Two-factor authentication, as it involves using something the user knows (username/password) and something the user has (facial recognition). The other options do not specifically describe the authentication method being utilized in this context.
